摘　　要：针对传统机械安全起爆系统的可靠性计算方法不能适用于电子安全起爆系统的问题,提出次数折合时间的电子安全起爆系统可靠性计算方法。该方法以环境系数确定环境因子,将累计等效工作时间折合为累计等效工作次数,再按照类推的工作次数指数模型计算得到电子安全起爆系统的可靠度单侧置信下限。通过数据计算比较,无故障工作次数增加,可靠性提高,证明方法有效。The method for calculating the reliability of traditional mechanical safety detonating system is not suitable for electronic safety and arming devices（ESAD）reliability calculation.This paper proposed a method to calculate the reliability of ESAD by using system operation times.By this method,the environmental factors were determined,the cumulative equivalent working time was converted into equivalent operation times,and then followed the operation times exponential model,the one-sided lower confidence limit of reliability of elec-tronic security initiation system was obtained.By comparing data calculations,the method could get more datas, and was more reliable.
